Atropine did not appreciably affect autoregulatory response, but intravertebral injection suppressed the increase of cerebral blood flow (CBF) by inhalation of 5% CO<jats:sub>2<\/jats:sub> and enhanced the decrease of CBF induced by hyperventilation. These changes produced by intravertebral injection of atropine were not observed after intravenous injection. Since the vertebrobasilar arterial system supplies the brain stem and diencephalon, this suggests that a central vasodilator tonus of the cerebral vessels is maintained by the innervation of the cerebral vessels by cholinergic neurons which have their central origin in the brain stem and diencephalic area.<\/jats:p>","DOI":"10.3171\/jns.1975.43.6.0676","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T15:02:40Z","timestamp":1241708560000},"page":"676-688","source":"Crossref","is-referenced-by-count":26,"title":["Neurogenic control of cerebral blood flow in the baboon"],"prefix":"10.3171","volume":"43","author":[{"given":"Yasuo","family":"Kawamura","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John Stirling","family":"Meyer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hideharu","family":"Hiromoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minoru","family":"Aoyagi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yukio","family":"Tagashira","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erwin O.","family":"Ott","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Arch Neurol Psychiatry","doi-asserted-by":"publisher","first-page":"1257","DOI":"10.1001\/archneurpsyc.1932.02240060016002","article-title":"Cerebral vasodilator nerves and their pathway from the medulla oblongata with observation on the pial and intracerebral vascular plexus.","volume":"28","author":"Chorobski","year":"1932"},{"key":"b2","series-title":"The Pharmacological Basis of Therapeutics","first-page":"528","year":"1970"},{"key":"b3","series-title":"Med Res Eng","first-page":"13","article-title":"Continuous recording of human cerebral blood flow and metabolism.
